The CXSD6203 is a current mode monolithic buck switching regulator. Operating with an input range of 4.6-20V, the CXSD6203 delivers 3A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, regulators operate in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit. The CXSD6203 guarantees robustness with short-circuit protection, thermal protection, start-up current run-away protection, and input under voltage lockout. The CXSD6203 is available in an 8-pin ESOP package, which provides a compact solution with minimal external components
